IMPROVEMENT IN TABLE-SLIDES.

Specification forming part of Letters Patent No. 127,302, dated May 28,1872.

To all whom it may concern:

Beit known that I, WILLIAM J. BODA, of Dayton, in the county ofMontgomery and in the State of Ohio, have invented certain new anduseful Improvements in Extension-Table Slides; and do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing making a part of thisspecification, in which-- Figure 1 is a plan view of the upper side ofmy slide when closed; Fig. 2 is a like view of the same when extended;Fig. 3 is a side elevation of my device, as shown in Fig. 2; and Fig. 4is a cross-section of the same on lines 00 :v of Figs. 1, 2, and 3.

. Letters of like name and kind refer to like parts in each of thefigures.

My invention has for its object the production of a supporting slide orconnection for the frame of extension tables, which shall be simple inconstruction, cheap, and durable; and to this end it consists in thepeculiar construction of the contiguous or hearing faces of the slidingbars, by means of which the same are held in lateral contact while freeto move longitudinally, substantially as is hereinafter specified.

In the annexed drawing, A, A, and A represent three wooden bars,arranged in parallel lines, theinner or contiguous sides of which areeach provided with four faces, a and a, which have the same angle ofinclination from a vertical line, (preferably thirty degrees,) but arearranged in pairs, having, relatively, opposite angles, while the facesof each pair have different planes, and are connected by a third face,a,placed at a right angle to the lines, transversely, of the same. Theresult of this construction is the production upon one bar of a tongue,B, having the peculiar dovetail angular form shown, while within thecontiguous face of the adjacent bar is formed a groove, B, whichcorresponds to and receives said tongue, and firmly unites said parts,laterally, while permitting them to move freely in a longitudinaldirection.

The peculiar construction of the bearing. A

sides of the bars is effected by means of an ordinary tenoning-machine,provided with two cutter-heads, which have relative angles thatcorrespond to the opposite faces, or one-half of said faces may beformed at one operation, and the bar then reversed so as to. completethe opposite side, but in either case the labor and expense are buttrifling, while the strength and durability of the joint are fully equalto those composed wholly or in part of metal.

Having thus fully set forth the nature and merits of my invention, whatI claim as new The slide-bars A, A, and A, having their bearing-facesconstructed and connected together, substantially as and for the purposespecified.

In testimony that I claim the foregoing I have hereunto set my hand thisa7tl1 day of July, 1871.
